Local renovation guide

Renovation of your home in Horsens.

Horsens is Denmark's 7th largest city — a fjord city with an industrial heritage, a prison turned cultural venue, and a housing stock largely built during the post-war growth years. 47% of the city's homes were built in the 1960s–70s and are approaching the end of their service life for roofs, windows and installations. Horsens is a growing city with rising property prices — renovation is typically a good investment here.

Horsens in brief — context for your renovation.

waterA fjord city with salt and moisture

Horsens lies at the inner end of Horsens Fjord. This gives the waterfront a distinctive character — and means that houses close to the fjord are exposed to more moisture and salt. Check façades and windows on homes in these neighbourhoods with particular care.

location_cityA growth city in Jutland

Horsens is one of Jutland's most important growth cities. The transport hub has relocated here, and electronics industry and logistics are prominent. This gives a healthy housing market — renovation in Horsens is typically a good investment. A well-renovated home with an energy rating of B sells quickly and at a good price.

Fjernvarme Horsens A/S covers most of the urban area. If you have an oil boiler, connecting to the district heating network is almost always the best solution — contact fjernvarmehorsens.dk to check whether your address is in the supply area.

Your housing type.

Detached house from 1960–1985

47% of homes in Horsens — approx. 23,162 dwellings (source: Statistics Denmark 2025)

Detached houses dominate Horsens and are the largest housing category. The typical home is a brick house with a pitched roof from the 1960s–80s. Many are now approaching the end of their service life for roof, windows and installations.

Common weaknesses
